Adjustments to Shopify Context Theme

Dear all, we're looking to make a couple of design adjustments to our shopify webshop that probably require changes to the code. We're using shopify's context theme. Specifically we have the following things that we want to change: - We have shirts in different colors that are all listed as separate products. On the product page of each product the customers can also select the different available colors. We now want to create a link to the product page of the other color if a different color is selected. (see product page on our website: [login to view URL]) - Currently the number of shirts is just inserted as a free text. We want to change that into an numerical counter (also see link above). - On the overview for all collections we want to show all products for each collection below. Please refer to the mockup to get an idea. It is important that each section shows all products of the respective collection (on the mock-up there are only 6 for "Business Unterhemden" even though it should be 12). Additionaly, if the customer clicks on one of the collection pictures, the site should automatically scroll down to the respective detail section below. Lastly, the word above the pictures should be changed from "Kategorien" zu "Perfekte Unterwäsche." Looking forward to receiving your quotations.
